Throttle Controls

Throttle controls are responsible for managing the engine’s air and fuel intake, which in turn dictates the power output and speed of the vehicle. They allow the driver to regulate the engine’s performance and increase responsiveness by controlling the amount of air and fuel mixture entering the engine. Throttle controls are crucial components of the air and fuel system and require frequent maintenance to keep the system working properly.

The system starts with the accelerator pedal, which the driver operates to send a signal to the Engine Control Module (ECM) or the throttle body to increase power output. A throttle body is a valve located between the air filter and the intake manifold that controls the amount of air entering the engine. In mechanical throttle control systems, the throttle body is connected to the accelerator pedal by a cable.

Throttle controls also involve a wide range of sensors and measuring devices like the Throttle Position Sensor (TPS), which monitors the position of the throttle valve and send the information to the ECM that adjusts the air-fuel mixture for optimal performance.

Maintaining the throttle control system in your truck or semi is essential for keeping the engine operating smooth, retaining precise vehicle control, and increasing fuel efficiency. Regular inspections, cleaning, and servicing of your throttle controls - along with all of its components - can help prevent performance issues and malfunctions in the long run.
